Huygens wave theory:
Huygen's wave theory is not correct in all respects.
2. It assumes simply that light energy is propagated as a wave.3. At the time of his proposition Huygen's did not have any idea about wavelength or about the transverse nature of light.4. So Huygens wave theory was Later modified by Thomas Young and Fresnel.5. They introduced the concept of wavelength and assumed that light waves are transverse.6. By these assumptions they could successfully explain not only the rectilinear propagation of light but also the phenomena of interference, diffraction and polarization of light.
What do you mean by understand by the statement ‘charge is quantized'? The electric lines of force do not intersect. Why?
Inertia and Mass: Newton's 1st law of motion describes that "an object at rest stays at rest and an object in motion stays in motion with the similar speed in the similar direc
Why the velocity of light is limiting velocity of anything.
It is the force that the field would exert on any unit magnetic pole placed in the field. It is also known as magnetic force.
